Cosmic-Ray Heating and Molecular Cooling of Dense Clouds (original) (raw)
NASA/ADS
Abstract
We estimate the heating by low-energy cosmic rays of molecular clouds whose main constituent is H2 to be 19 eV per primary ionization. We determine the steady-state temperature as a function of density where H2 and CO are responsible for cooling for a range of ionization rates and CO abundances.
